Answer To CP Review HW For LDS Of Covalent Bonding Substance

ai) Lewis Dot Structure (LDS), picture that shows what element is sharing valence electrons (ve^-) and how many ve^- are not shared around each atom.
aii) VSPER - changes LDS into shapes/geometry of substance

aiii) Hybridization - theory behind concepts


b) Molecular compounds (MC) and polyatomic ions

c) No LDS is based on pairs of ve^-

d) Number of Column (counting Left to Right not including D and F block elements).

e) After bonding (determining shared and lone pair for each element) All element want 8 ve^- around then except H ( 2ve^-), Be (4 ve^-) and B (6 ve^-)
fi) Same outside atoms (non-central atom)
fii) Two different types of bonds (i.e. 2 single and 1 double bonds)

Part II

1a) Total # of ve^- = 18ve^-
1b) You draw
1ci) N is central atom and 1 LP
1cii) 1 double and 1 single bond (Resonance structure and need [ ] since it is ion)

2a)Total # of ve^- = 18ve^-
2b) You draw
2ci) O is central atom and 2 LP
2cii) 2 single bonds

3a)Total # of ve^- = 26ve^-
3b) You draw
3ci) S is central atom and 1 LP
3cii) 3 single bonds (need [ ] since it is ion

4a)Total # of ve^- = 32ve^-
4b) You draw
4ci) C is central atom and 0 LP
4cii) 4 single bonds
